Important Note:
If upgrading an older Osburn 1600 configuration that used refractory bricks (29020), installation may require configuration changes such as removing a center support. Always confirm your stove’s internal layout and follow your owner’s manual for proper baffle and insulation placement.

Why Choose the Lynn Manufacturing 2501C Baffle Kit?
Worn or damaged baffles and insulation blankets can reduce efficiency, disrupt secondary combustion, and increase emissions. The 2501C baffle kit restores proper airflow and insulation above the fire, helping your Osburn stove burn cleaner, hotter, and more efficiently—whether you’re replacing original components or upgrading an older baffle configuration.

Installation Instructions:
Allow the stove or insert to cool completely before servicing. Ensure all embers are extinguished.
Remove the baffle access components as required to reach the baffle area (varies by model).
Carefully remove the old baffle boards and insulation blankets or refractory brick setup if present.
Clean the baffle support ledges and inspect for warping, damage, or heavy creosote buildup.
Install the two new baffle boards in the same orientation as the originals, ensuring they sit flat and fully supported.
Place the two insulation blankets above the baffle boards, covering them evenly without gaps.
Reinstall any removed components and confirm the baffle system is secure before operating the stove.

Installation Tip:
Never operate your stove without the baffles and insulation installed correctly. Improper baffle placement can reduce heat output, increase smoke/creosote, and overheat internal components.

Keep your Osburn 1600 Series stove burning efficiently with the Lynn Manufacturing 2501C Baffle Kit—engineered for high heat performance, reliable fit, and long-term durability.
